Chandra Deep Field South: 2000 and 2007 Observations (Superseded)
The old 2000 and the new 2007 data from the Chandra Deep Field South have been custom processed to register all 21 individual observations astrometrically. For more information, see the README file.
On 2008-05-01 we have added a new set of merged products, for the 2007 data only, where background events were further removed using the 5x5 pixel event island available in VFAINT mode. For more information, see the updated README file
We offer these types of products for download:
- Merged tar file containing the merged event file, exposure map, and image
- By-ObsId tar file containing the event list and aspect solution for each of the individual ObsIds
- Full resolution linear three-color image of merged datasets
- Full resolution enhanced three-color image of merged datasets
- Smoothed enhanced three-color image of merged datasets
